Application fileil May 19, 1904. Serial No. 208,655.

city of Newark, county of Essex, in the State of New Jersey, haveinvented certain new and useful Improvements in Tires, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part hereof It is the object of this invention toprovide means for increasing the etliciency as well as the life ofrubber tires for vehicles' Under the conditions of use which prevailto-day such tires are rapidly destroyed, owing to rough pavement,punctures from various causes, and the wear produced by other causes towhich these unprotected soft-rubber tires are exposed. Furthermore,onsmooth wet pavements the tires are constantly slipping, and the controlof the machine is not only rendered imperfect, but the tractive force ofthe drivingwheels is materially lessened.

To overcome such objections and ditticulties connected with the use ofrubber tires, a particular form of tire-covering has been devised by me,which covering will now be described.

[n the accompanying drawings, in which the invention is illustrated,Figure l a view in side elevation of a sutlicient portion of a wheelwith the improved device secured to the rim thereof to enable theinvention to be. understmnl. Fig. 2 is a view in central sec.- tion ofthe wheel on a smaller scale: and Fig. 3 is a diagrammatic view inprojection of a portion of the improved tirecover, illustrating themanner of weaving the same.

The improved cover is essentially a network or webbing which extendsaround the whole of the exposed part of the tire, as shown in thedrawings. It may be secured to the wheel in various ways. As illustratedin Fig. 1, eyelets are provided in one edge of the cover andcorresponding turnlnickles 7/ in the other edge thereof, the turnbucklesbeing brought through the eyelets over the inner side of the rim of thewheel when the cover is to be fastened thereto. It will be obvious,however, that the cover may be laced to the rim or that certain of thestrands thereof may be extended so as to be tied or otherwise fastenedaround the rim, as desired.

The network comprising the cover is made up of circular longitudinalstrands or rings (3, preferably endless strands or rings, and atransverse strand or strands (I, which are woven with the longitudinalstrands to hold them together. The longitudinal strands are of differentdiameters, Fig. 2, according to their position in the cover. growingsmaller as the strands approach the edge of the cover, so that the shapeof the completed cover is that of a circular band bulging in thecenterthat is, the usual shape of the periphery of an ordinary tire. Inorder to weave this circular band of network or webbing in the form justspecilicd and to bring the bulk of the material in the cross strand orstrands near. the center of the tire or cover where the greater wearwillcome, the following method of weaving is preferable: Assuming thatthe longitudinal strands a and f, Fig. 3, are the central strands of thecover and that the longitudinal strands .2 and are the strands at theedges of the cover, starting with a crossstrand (2 at one edge, saidcross-strand is brought under strand 7", over strand under strand /1,over strand under strand over strand Z, under-strand overstrand 11/,around strand )1; under strand 11/, over strand 7, un der strand 1',over strand j, under strand f, overstraml /I, understrand 5/, aroundstrandf'; over strand y, under strand /I, over strand I, under strand j,over strand 1', under strand around strand m: overstrand under strand A,over strand j, under strand 1', over strand /1, around strand understrand It, over strand under strand j, over strand Z, around strand 1:under strand Z', over strand j, under strand 1', around strand overstrand 1', un der strand j, around strand l: over strand J, aroundstrand around strand j.- under strand X, around strand /l,' over strandZ, under strand j, around strand Z; over strand j,

under strand 1', over strand ll, around strand under strand /l, &c.,until the transverse webbing reaches the outer edge of the tire, Thesame cycle is repeated and continued un til a perfectly circular bandhas been woven. it will be understood that varying shapes of tires orwheels or other conditions may renl center of the wheel, the portionwhere most der different methods of weaving desirable or necessary. Forinstance, to have the cover fit closely against the tire it will benecessary always to have the varying diameters of the longitudinalstrands on the rings correspond with the different diameters of the tireperiphery. It will be understood, too, that one strand or severalstrands may be used to weave the longitudinal strands together.

The material of which the strands are composed may be any form of ropeor the like and the proper size and thickness to suit the conditions ofuse for which it is desired. For light vehicles it will be obvious asmaller and probably a finer rope would be used than upon a large truck.The invention, however, is not limited to any particular material or toany particular dimensions of that material. In securing the cover aboutthe tire the nature of the material of which the cover is composedshould permit it to be stretched sufficiently to be slipped intoposition. It is then secured and tightened around the tire by theparticular means which have to be prepared for the purpose. Forpneumatic tires a cover slightly smaller than the inflated tire will beused, and it will be secured to the rim preferably when the tire isflat, whereupon the tire may be inflated to fill the space between therim and the cover.

The advantages gained by the use of the cover will be clear. Thetractive force of the driving-wheels will be considerably increased whenwet pavements are encountered, particularly on account of the transversestrand or strands which are most numerous at the of the wear comes. Thetire will be preserved from punctures, gouges, and other injuries whichtend to destroy the same, inasmuch as the covering is tough and willhave to be penetrated before the tire is encountered. Accordingly thetire will serve its purpose much more efficiently, and its life will beconsiderably prolonged.

I claim as my invention 1. A tire-cover comprising a network having aplurality of longitudinal strands, and a transverse strand woven backand forth across the longitudinal strands so as toinclude a larger orsmaller number of longitudinal strands each time it crosses thelongitudinal strands.

2. A tire-cover comprising a network having a plurality of longitudinalstrands, and a transverse strand woven back and forth across thelongitudinal strands so as to include one less longitudinal strandtoward the edge of the cover each time it crosses the longitudinalstrands.

3. A tire-cover comprising a network having a plurality of longitudinalstrands, and a transverse strand woven back and forth across thelongitudinal strands under one and over the next so as to include oneless longitudinal strand toward the edge of the cover each time itcrosses the longitudinal strands.

This specification signed and witnessed this 16th day of May, A. D.1904.
